Schneider Electric Test Engineer Interview Questions and Answers

Q1. What is Power factor
Ans. 
Power factor measures the efficiency of electrical power usage, indicating how effectively electrical energy is converted into useful work.
• Power factor (PF) is defined as the ratio of real power (kW) to apparent power (kVA).

• A power factor of 1 (or 100%) indicates all the power is being effectively converted into work.

• Low power factor can lead to increased energy costs and reduced system capacity.

• Example: A motor with a...read more
